The “investigation of the @ALT_uscis account plainly has nothing whatsoever to do with the importation of merchandise into the United States,” Twitter’s lawyers wrote. The company went on to argue any unmasking of the account would have a chilling effect on users critical of the Trump administration, and by extension, free speech. The owner of the @ALT_uscis account directed a reporter to attorney Esha Bhandari of the ACLU Speech, Privacy, and Technology Project. Bhandari declined to say when she first came into contact with Twitter and the account holder, whom she is representing. There are instances in which Twitter will share non-public information about its users with law enforcement, the company says in its guidelines.
